A website used by married people to have affairs was accessed hundreds of times a day by MPs, peers and their staff, it has been revealed.

Out Of Town Affairs was clicked on more than 52,000 times in seven months from computers at Parliament – more than the websites for the Treasury, Ministry of Justice and the Department for Education.

Robert Oxley, of the TaxPayers’ Alliance, said: ‘Taxpayers expect parliamentarians to spend time making laws and scrutinising the government, not trawling dating websites.’

A Parliamentary spokesman said more than 5,000 people had access to its computer network.

It has now blocked access to the dating website.

The owner of Out Of Town Affairs told The Mail on Sunday: ‘That’s a lot of hits. It’s got to be more than one person going on the site from Parliament. I hope we don’t get hate mail from parliamentary wives now.

‘It’s an adult dating site, but you market it as an affairs website because that’s where all the Google searches come from.’
